I do as https://wiki.videolan.org/VLCKit/#Build ... rk_for_iOS said, and I drag the libMobileVLCKit.a and header files from VLCKit/build/Release-iphoneos to Xcode. But when I build the official sample project "SimplePlayback", Xcode log

I don't know why.

Check for nightly builds.
http://nightlies.videolan.org/build/ios/
Last one is 700k size
and 2014-12-08 build is 180 Mb.

So just take the full build and wait for a fix...

The problem is still exist in the lasted build. It seems only happen when building with real device. Here is my logs:

Undefined symbols for architecture armv7:
"_celt_pitch_xcorr_neon", referenced from:
__celt_autocorr in libMobileVLCKit.a(celt_lpc.o)
_pitch_search in libMobileVLCKit.a(pitch.o)

Can you still reproduce the issue with this morning's build?

Posted: **16 Dec 2014 09:12**

Hi Felix,

Do you mean MobileVLCKit-UniversalBinary-20141215-0620.zip 2014-12-15 06:25 186M, right?. If so, the problem is still there

Posted: **16 Dec 2014 12:33**

OK, I'll try to reproduce this tonight. I'll follow-up with you later.

The bug happens on master branch from commit: 4ef02b6b899890135569dd65a41acbea9c8f03dd (MVK: drop 7 patches, adapt to new build script, update libvlc hash)

Posted: **17 Dec 2014 12:32**

Yep, we enabled ARM assembly code in libopus and for some reason, it fails to include a symbol for that in the static library. I'm working with the OPUS team right now to solve this issue.

Hi Felix, hope you don't forget this one

is there any update for this?

Posted: **20 Dec 2014 15:19**

Yes, I pushed the fix about a minute ago and triggered the build bot to create an updated binary for you to test.

Posted: **20 Dec 2014 15:26**

Ok, due to a server issue, we cannot provide new builds of MobileVLCKit at this time. We hope to have those issues solved early next week.

Mery xMas

Is the build available for testing

Posted: **25 Dec 2014 14:35**

I just fixed the hopefully last remaining issue and dispatched a build. Let's see if it succeeds.

Happy Christmas to you, too!

it works like a charm. Thanks Felix
